Thank you, Daron. I'll now provide a look at our consolidated financial results as well as guidance about our expected revenues in 2019. I'm also going to cover an important result in our water filtration business segment. And then I'll give an update on our plans to up list to a National Exchange. I'll begin again with the consolidated financial results. I'm very pleased to report that this quarter represents our 10 consecutive quarter of year-over-year total revenue growth averaging 56%. As we spend consistently. We believe that this steady fast revenue growth is indicative of Nephros's strong product portfolio, the increasing market awareness of our brand, our deep relationships with partner companies in the field and the increasing regulations requiring water testing and remediation. We reported total revenues of 5.7 million in 2018, compared to 3.7, I'm sorry, 3.8 million in 2017. That's an increase of 1.9 million or 50%. Product revenue for the year was 5.5 million, compared to 3.5 million last year with rounding it was an increase of about one 1.9 million or 54%. Quarter-over-quarter product revenue growth was flat due to fewer than expected regional outbreaks in the fourth quarter. Cost of goods sold in 2018 were 2.5 million, compared to 1.5 million in 2017. That's an increase of a $1 million or 64%. Gross margins in 2018 were 56%, compared to 60% in 2017. We consider gross margin fluctuations between 55% and 60% to be normal for a business of our size and our growth rate. But having said that, our 2018 gross margins were lower than expected due to a one-time inventory adjustment in the first quarter of 2018 as previously reported. Research and development R&D expenses were approximately 1.5 million in 2018, compared with 1 million in 2017, a 54% increase. Quarter-over-quarter R&D growth was consistent with the trend with that trend for the year at 55%. The R&D increase over last year over 2017 is due to increased investments in the second generation HDF machine through our specialty renal products or SRP subsidiary. Selling general and administrative expenses, or SG&A were $4.5 million in 2018 compared to $3.3 million in 2017, an increase of $1.2 million or 37%. Quarter-over-quarter spend in SG&A increased 3%. Our cash balance at the end of 2018 was $4.6 million. A significant increase from our 2017 cash balance of $2.2 million. This increase was largely driven by two separate private placements during the year one for Nephros on April 10, 2018 and the second for our SRP subsidiary on September 6, 2018. We believe our cash balance is sufficient to fund operations for at least another year. And we have no specific plans to raise capital at this time. Based on our 2018 results and our strong sales pipeline, I am pleased to provide guidance with 2019 revenues between $8.5 and $9.5 million, which would be an increase of 50% to 65% over 2018. I now want to turn to a particular result in our water filtration business segment. As a reminder, we now recognize two distinct business segments within Nephros, water filtration and renal products. Water filtration is a 100% of our current revenues which have approximately tripled over the past three years. Our renal products business on the other hand is a development stage business, which Daron will discuss again a little later in the call. Begining with today's press release and earnings call we will track and report on a new non-GAAP metric for the water filtration business which is adjusted EBITDA or earnings before interest, taxes, depreciation and amortization. This metric is calculated by taking GAAP net income or loss and excluding all interest and related and I'm sorry -- all interest and tax related expenses and income as well as other non cash items. This calculation and reconciliation to GAAP net income or loss is further detailed in today's press release. Adjusted EBITDA for the water filtration business segment in 2018 was negative $860,000 I’m pleased to report however, that the trend in this metric was quite strong, transitioning from negative 686,000 in Q1 to negative 292,000 in Q2, to negative 18000 in Q3, and finally to positive 137,000 in Q4. While this metric may fluctuate, we do expect positive adjusted EBITDA in 2019. I’ll now turn our – my attention to the up list process and give you an update on that. As many of you know it was our intention to up list to a national exchange in late 2018. Our efforts have been delayed by several factors, including a minor technical accounting issue that has been resolved and changes in our board of directors. Our intention to up list has not changed. We expect to do so this year, including the previously announced reverse stock split and we will keep you informed as the process continues. I will now turn the call back over to Daron, who will touch on our HDF business and then open the call for your questions. Thanks.
